[Bug fortran/40246] ICE on invalid SOURCE= using NULLIFY

[burnus at gcc dot gnu dot org]

------- Comment #1 from burnus at gcc dot gnu dot org  2009-05-26 08:32 -------
The following patch to gfc_match_nullify fixes it; however, I think one should
additionally add

  gfc_free_expr (new_st.expr1);
  new_st.expr1 = NULL;
  gfc_free_expr (new_st.expr2);
  new_st.expr2 = NULL;

to prevent a memory leak.
